  irqchip/sifive-plic: set max threshold for ignored handlers (2019-09-05 01:59:55 -0700)

----------------------------------------------------------------
RISC-V updates for v5.4-rc1

Add the following new features:

- Generic CPU topology description support for DT-based platforms,
  including ARM64, ARM and RISC-V.

- Sparsemem support

- Perf callchain support

- SiFive PLIC irqchip modifications, in preparation for M-mode Linux

and clean up the code base:

- Clean up chip-specific register (CSR) manipulation code, IPIs, TLB
  flushing, and the RISC-V CPU-local timer code

- Kbuild cleanup from one of the Kbuild maintainers

----------------------------------------------------------------
